Set the function equal to zero: (f(x)=0)
Solve the resulting equation for (x)
Factor the function if possible
Use the zero product property if the function is factored
Simplify the equation before solving
Apply algebraic methods such as:
Completing the square
Quadratic formula
Square root property
Rational root theorem
Graph the function and find where it crosses or touches the x-axis
Use a table of values if needed
Check solutions by substituting them back into the original function
Exclude any extraneous solutions if they appear
